好像我调试总是错误，找不到错再哪，帮下

#include <stdio.h>
int main(void)
{
int time1, time2, hour, minutes;
int a , b ,c ,d;
scanf("%d%d", &time1, &time2);

a=time2%100;
b=time1%100;
if(a>b){
minutes=a-b;
}
else{
minutes=60+a-b;
}

c=(time2-time2%100)/100;
d=(time1-time1%100)/100;
if(c>d){
hour=c-d;
else{
hour=24+c-d;
}

printf("The train journey time is %d hours %d minutes.\n", hour, minutes)
}

第二个if后面应该有一个"}"
printf语气括号后面需“；”
前面有int main声明的最后需有一个返回值，即return 0；
修改后的程序如下：
#include <stdio.h>
int main(void)
{
int time1, time2, hour, minutes;
int a , b ,c ,d;
scanf("%d%d", &time1, &time2);

a=time2%100;
b=time1%100;
if(a>b){
minutes=a-b;
}
else{
minutes=60+a-b;
}

c=(time2-time2%100)/100;
d=(time1-time1%100)/100;
if(c>d){
hour=c-d;
}else{
hour=24+c-d;
}

printf("The train journey time is %d hours %d minutes.\n", hour, minutes) ;
return 0;}
